It may be very tricky thing to get papervision 3d scene rendered correctly event for the simpliest objects. In my case, I have created simple 3d scene with few primitive objects (8 cubes). Cubes are positioned close to each other to create shape of bigger cube + some small space between. Cubes are added into wrapping DisplayObject3D, later wrapper is added to scene in order to make it easy to rotate cubes as a group. Camera targets the center of the scene. In the demo, there are 3 sliders to rotate wrapping object in each x, y, z axis + two buttons that rotates wrapper in the problematic possition (based on z-sorting fix approach). Finally I managet it to work, you can follow my approaches below. Notice the changes are not cummulative, each approach comes from original Application.mxml. All of the ideas collected online from blogs, forums etc.

I guess it’s worth noting here that since setting useOwnContainer=true may give some troubles with DisplayObject3D instances registered to InteractiveScene3DEvent.OBJECT_CLICK events – basically those instances become sort of numb to previously registered OBJECT_CLICK events – changing OBJECT_CLICK to OBJECT_PRESS makes everything work like a charm.
